Interesting story Joe. That's nice to know. Knowing more than one language is always a nice virtue to have.
Honestly, I'm not a fan of the Brazilian Portuguese. It just misrepresent all the Portuguese words, when in fact, Pedro Álvares Cabral, a Portuguese nobleman, military commander, navigator and explorer was the one that discovered and explored Brazil way back in 1500.
Here is a link to the story if anyone is interested: https://en.wikipedia.org/wiki/Pedro_%C3%81lvares_Cabral
Although it's easier for those who speak English and want to learn Portuguese, because the way it's spoken, is like a mix between English accent and Portuguese words, which makes an interesting combo for a Portuguese ear.
Lathe chucks always have their jaws numbered with the matching number marked on the chuck body. If you look closely on your chuck jaws, you might find it in one of the side slots. On the body, is usually marked on the outside diameter or on the flat spot just above the scroll, under the jaw.
Sometimes, on used chucks, the first tooth of the jaw is broken because someone just tried to chuck something to big for the chuck, so the jaw only engages 1 tooth on the scroll. When reinstalling the jaws, this require some thought to make sure the jaws go in properly.
Another thing I noticed, is that your chuck only have one pinion, hence why it's a bit more consistent. Most 3 jaw chucks have 3 pinions and it's advisable to tighten all three with more or less the same torque, so the part runs concentric.
Here is a diagram of the lathe components so we all can understand each other.
